https://doi.org/10.1351/goldbook.S05867
A second-order transition from a paramagnetic or ferromagnetic state to a spin-glass state in which spins from moment-bearing solute atoms become ordered randomly in a non-magnetic host such that the net magnetization of any region is zero.,Examples: AuFe, CuMn and MoFe
